Structural element for a motor vehicle
View Patent ↗The invention relates to a structural element ( 100 ) of a motor vehicle, in particular of a motor vehicle seat, wherein the structural element ( 100 ) comprises a first component ( 101 ) and a second component ( 102 ). In an overlap region ( 103 ), the first component ( 101 ) and the second component ( 102 ) have a formed-closed connection, or a form-closed and form-closed connection, wherein the connection in the overlap region ( 103 ) can be produced by an electromagnetic pulse shaping method, wherein the first component comprises at least one form-closed molding ( 600 ), wherein the second component can be molded into the at least one form-closed molding ( 600 ).
1. A structural element for a motor vehicle seat, wherein the structural element has a first component and a second component, wherein the first component and the second component have an interlocking or an interlocking and frictional connection in an overlapping region,
wherein the first component has a polygonal cross section, at least in the overlapping region;
wherein the connection in the overlapping region is produced by an electrically conductive driving method element arranged in a direction outside the first component and the second component;
wherein the first component has at least one interlocking molding on at least one wall of the polygonal cross section in the overlapping region,
wherein the second component is molded into said at least one interlocking molding by a radially inwardly acting force by the electrically conductive driving element,
wherein the at least one interlocking molding of the first component is designed in the overlapping region as an impression, wherein the impression is arranged at an angle of between 44° and 46° with respect to a main direction of extent of the first component.
2. The structural element as claimed in claim 1 , wherein the second component comprises an electrically conductive material, a steel material, an aluminum material or a magnesium material or a material consisting of material-to-material bonding connections of different materials.
3. The structural element as claimed in claim 1 , wherein the impression has an impression depth which varies in the longitudinal direction of the impression.
4. The structural element as claimed in claim 1 , wherein the first component has at least two interlocking moldings in the overlapping region, wherein the interlocking moldings are arranged at a uniform spacing of an angle at a circumference from one another.
5. The structural element as claimed in claim 1 , wherein the first component has the interlocking molding and at least one further interlocking molding in the overlapping region, wherein the interlocking molding and the further interlocking molding are designed as impressions having in each case a longitudinal direction, wherein the longitudinal directions of the impressions are arranged parallel to one another.
6. The structural element as claimed in claim 1 , wherein the first component has a hexagonal or octagonal cross section at least in the overlapping region.
7. A hybrid structural component of a motor vehicle seat comprising the structural element of claim 1 , wherein the structural element has a first structural part and a second structural part, wherein the first structural part is connected to the second structural part by an electromagnetic pulse shaping method, wherein the first structural part comprises a lightweight construction material and the second structural part comprises a steel material.
8. The hybrid structural component as claimed in claim 7 , wherein the first structural part is further connected to the second structural part in a cohesively bonded manner or the structural parts are coupled to each other by a clip and/or a strap.
9. The hybrid structural component as claimed in claim 7 , wherein the second structural part comprises a lightweight metal or a fiber-reinforced material reinforced with carbon fibers and/or glass fibers.
10. A structural element for a motor vehicle seat, wherein the structural element has a first component and a second component, wherein the first component and the second component have an interlocking or an interlocking and frictional connection in an overlapping region,
wherein the first component has a polygonal cross section, at least in the overlapping region,
wherein the connection in the overlapping region is produced by an electrically conductive driving element arranged in a direction outside the first component and the second component,
wherein the first component has a plurality of interlocking moldings on at least one wall of the polygonal cross section in the overlapping region,
wherein the second component is molded into the interlocking moldings by a radially inwardly acting force by the electrically conductive driving element, and
wherein the interlocking moldings of the first component are designed in the overlapping region as an impression, wherein the impression is arranged parallel or perpendicularly to a main direction of extent of the first component.
